Definitions

  • the present invention relates to an article transport bag, in particular of the take-away fast food type, comprising a bottom and lateral sides defining internal walls delimiting an internal storage space.
  • this type of bag is made of paper, such as kraft paper, or plastic.
  • the preferred field of application of the present invention is therefore that of packaging and transport of various articles, and more particularly ready meals and drinks.
  • this type of article transport bag is produced from a sheet roll which is fed through a whole series of roll forming machines to ultimately constitute an article transport bag. More particularly, a first series of roll forming machines makes it possible to wind and close the sheet on itself to form a continuous cylinder. Then, a second series of roll forming machines makes several folds, like an envelope, to form the bottom of the bag. Optionally, it is also possible to integrate cuffs, in particular by gluing, upstream of the first series of roll forming machines. In the end, a bag is obtained whose lateral sides form a cylinder or a closed loop on itself, while the bottom is obtained by successive folding and gluing, generally in the manner of an envelope. This is a completely classic or conventional design for a fast food take-out type bag.
  • the items ordered by the customer are placed on the bottom of the bag in a standing position.
  • the customer thus leaves with his bag filled to the place where he has decided to consume what he has just bought.
  • the user can take the articles out of the bag to place them on a table.
  • Some customers have become accustomed to tearing the bag along the edges which connect the lateral sides.
  • the bag has the shape of a cross with four branches with the bottom constituting the central part.
  • the items purchased can then be placed on this torn and unfolded bag.
  • the cross shape of the tablecloth gives a patchy coverage, and there is a risk of contaminating the surface underlying the bag / tablecloth between the lateral sides arranged in a cross.
  • the bag makes it possible to constitute a tablecloth, and its effectiveness is very limited.
  • FR2813292 which describes a bag made of a sheet in one piece and forming a bottom, four lateral sides, as well as connecting sectors connecting two adjacent lateral sides.
  • the connecting sectors are folded in the manner of a fan or a bellows under the action of a string which will also serve as a wrist.
  • this sachet is in its unfolded flat state, it offers a covering surface similar to a square tablecloth with rounded corners. Therefore, this particular bag includes a bottom in one piece (not obtained by folding) and side walls which are connected together, not continuously, but through the connecting segments.
  • the document EP1595811 A1 describes a paper bag formed by a sheet wound in a continuous cylinder of rectangular section and provided with bellows in the corners allowing an enlargement of the bag.
  • the present invention aims to remedy the aforementioned drawbacks of the prior art by defining another type of unfoldable bag in the form of a sheet but the manufacture of which makes it possible to be automated, in particular on a production line as described above. .
  • Another object of the present invention is to produce a bag whose starting structure before folding is different from its final structure after unfolding.
  • Yet another object of the present invention is to be able to implement it without completely modifying the conventional design of conventional bags.
  • the present invention provides an article transport bag, in particular of the take-away fast food type, comprising a bottom and lateral sides defining internal walls delimiting an internal storage space, characterized in that '' at least one bellows element is attached in a folded state and fixed on at least one internal wall of the lateral sides at two adjacent fixing zones separated by a frangible zone provided at at least one lateral side, so to be able to bring the bellows element into an unfolded state after rupture of the frangible zone.
  • the bottom and the lateral sides are formed by a single monobloc sheet on which is fixed one or more bellows element (s) of the invention before being folded (s) to form the article transport bag.
  • the bag After rupture of the frangible zone (s), the bag can be opened by unfolding the bellows element (s). Consequently, the initial state of the bag before folding does not at all correspond to its final state after unfolding.
  • the bellows element (s) When the bag is formed, the bellows element (s) are completely inoperative, since they are prevented from unfolding by the frangible zones which are still intact. Therefore, the bag has, before rupture of its frangible zone (s), a completely conventional configuration with the lateral sides connected to each other continuously.
  • the bag with the lateral sides interconnected so as to form a continuous cylinder and the bottom formed by several folded overlapped sides, as explained above with reference to the conventional manufacturing machine.
  • the bellows element comprises a bellows, advantageously in the form of a quarter of camembert in the unfolded state and an eighth of camembert in the folded state, bordered by the two fixing flaps, which extend parallel adjacent to the folded state and at right angles to the unfolded state.
  • the bag can be provided with one, two, three or preferably four bellows elements which have the shape of a quarter of Camembert in the unfolded state and of an eighth of Camembert in the folded state.
  • the fixing flaps are adjacent and can be fixed, for example by gluing, on either side of the connecting edges which form frangible zones.
  • the frangible zone is formed at a lateral side, the two adjacent fixing zones being respectively provided on the lateral side on either side of the frangible zone.
  • the bellows element comprises two bellows each bordered by the two fixing flaps, advantageously in the form of an isosceles right triangle, which extend adjacent to the folded state and at right angles to the unfolded state.
  • the bellows element is made from a sheet having a width and a length which corresponds to four times its width so as to define four aligned squares, each square being folded along one of its diagonals.
  • the frangible zone comprising two frangible lines connected at an angle straight at a junction point, to which a frangible segment is advantageously connected, in particular in the form of a tear-away pulling strip, which extends over the height of the lateral side.
  • the bag can be provided with one, or preferably two, bellows elements arranged at the lower part of two opposite lateral sides, near the bottom.
  • the frangible segment and the two frangible lines together have a shape similar to an inverted Y.
  • the bag comprises from one to four bellows elements added and fixed astride one to four frangible zones produced at the lateral sides.
  • This manufacturing process can easily be implemented on a conventional manufacturing machine. This manufacturing process makes it possible to produce a bag according to the first or the second embodiment described above.
  • the spirit of the invention resides in the fact of attaching and fixing bellows elements inside the lateral sides of the bag and of providing frangible or breaking zones at the level of the lateral sides to allow the folding of the bag, rupture of the frangible zones and deployment of the bellows elements, so as to achieve a final configuration similar to a conventional ply.
  • FIGS 1a, 1b, 2a, 2b and 2c The first main component of this S1 bag is an F1 sheet, visible on the figure 1a , which here has a rectangular shape.
  • the sheet F1 can be made with any suitable flexible material, such as paper, suitable plastic, etc. It is common to use kraft paper for this type of bag.
  • the sheet F1 is shown on its face or inner wall F1i.
  • the sheet F1 defines several zones separated by fold lines F14 which will be used to form the bag and to condition it in a flattened manner.
  • the sheet F1 defines four side walls F12, F13 which are identical in pairs.
  • the two side walls F12 have a substantially square configuration, while the other two side walls F13 have a rectangular configuration.
  • the walls F12 and F13 are arranged one next to the other in an alternating manner.
  • the sheet F1 also defines sections F10 which extend parallel to the column of side walls F12, F13. These sections F10 will form after folding the bottom F11 of the bag S1, as will be seen below.
  • the sheet F1 also includes an assembly tab F16 which extends over the entire width of the side wall F12, as well as on the face F10. This assembly tab F16 will serve to constitute a closed cylinder by attaching it to the lower edge of the side wall F13 located at the bottom of the sheet F1.
  • the sheet F1 has a completely conventional configuration for an article transport bag, such as for example the bags used in fast food establishments to take away cooked hot dishes.
  • the lateral sides F12, F13 are connected to each other by frangible zones F15 which are easily breakable.
  • These frangible zones F15 are situated exactly at the level of the connecting edges connecting two adjacent lateral sides, once the bag has been formed. It could also be said that the connecting edges formed by the lateral sides of the bag are designed so as to facilitate tearing of the bag in a controlled manner.
  • These frangible zones F15 can be formed by a local reduction in the wall thickness of the sheet F1 or by a precut of this sheet. The precut can for example be carried out in a dotted fashion, or even more widely.
  • the frangible zone can for example be formed by cuts a few centimeters long separated by intact, weakened or precut areas.
  • the frangible zone can also be in the form of a strip or pull tab that the user will pull. Whatever the nature and structure of these frangible zones, their main function is to generate a controlled tear in the sheet F1, more particularly at the level of its connecting edges.
  • the frangible zones F15 can even extend at the level of the panels F10.
  • FIG. 1a it is also possible to identify several fixing zones Z14 and Z15 which are represented in dotted lines.
  • the first pair located at the very top of the figure 1 comprises an area F14 which extends over the assembly tab F16 and an area F15 which extends over the lateral side F12.
  • the other three pairs each extend on a lateral side F12 and a lateral side F13.
  • These zones Z14 and Z15 can be coated with glue. They can extend over the F10 panels.
  • the Figures 2a, 2b and 2c represent the bellows element E1 which is used to make the bag S1 according to the first embodiment of the invention.
  • the bellows element E1 is here produced from a piece of sheet, the nature of which may be substantially similar or identical to that of the sheet F1. They can be rigid or semi-rigid to increase the rigidity of the sides on which they are pressed and thus increase the stability of the sheet, once the bag is unfolded.
  • This piece of sheet has the shape of a quarter circle or quarter camembert with two straight edges arranged at right angles and a rounded edge in quarter circle which connects the two straight edges.
  • the bellows element E1 defines two bellows leaves S11 and S12, identical by mirror symmetry along a fold line S13.
  • the two bellows vent S11 and S12 are articulated relative to each other along the fold line S13.
  • Each bellows fan S11 and S12 forms an eighth of a circle or pie chart.
  • the bellows element E1 comprises two elongated fixing flaps S14 and S15 for fixing the bellows element E1 to the sheet F1, as will be seen below with reference to the figure 1b .
  • the elongated fixing flaps S14 and S15 extend at right angles to each other on the figure 2a , which corresponds to the initial or unfolded state of the bellows element E1.
  • the two elongated flaps S14 and S15 are then in contact with each other at an oblique end edge.
  • the shutter S14 is connected to the bellows fan S11 along a fold line, while the flap S15 is connected to the bellows fan S12 by another perpendicular fold line.
  • bellows elements E1 can be brought back in the folded state ( figure 2c ) on the sheet F1 so that the fixing flaps S14 and S15 of the same bellows element E1 are positioned respectively on a pair of fixing zone Z14, Z15 on either side of a frangible zone F15. It can thus be said that the two elongated fixing flaps S14 and S15 of the same bellows element E1 are separated by a frangible zone F15.
  • the first highest bellows element E1 on the figure 1b has its flap S14 fixed on the tongue F16 and its other flap S15 fixed on the lateral side F12. It can be noted that the tips of the flaps extend at the level of the panels F10.
  • the second highest bellows element E1 on the figure 1b has its flap S14 fixed on the side F12 and its other flap S15 fixed on the side F13.
  • the third bellows element E1 is fixed astride the side F13 and the side F12, while the last bellows element E1 is the lowest on the figure 1b is fixed astride the F12 side and the F13 side.
  • the fixing of the flaps S14 and S15 on the sheet F1 can be done by any suitable technique, such as gluing, or welding. It can thus be said that the sheet F1 defines attachment zones which extend along and on either side of the frangible zones F15. These areas are visible on the figure 4d which will be described below.
  • the bellows S1 can be folded over each other in pairs, as shown in the figure 1b .
  • the leaves S11 and S12 can be folded down on the large lateral sides F12, leaving the small lateral sides F13 free.
  • the sheet F1 can be rolled up and closed on itself by fixing, for example by gluing, the assembly tab F16 on the lower edge of the lowest lateral side F13 of the figure 1b .
  • a cylinder is thus formed which can be folded appropriately in order to constitute the bottom of the bag using the F10 sections.
  • the bag S1 according to the first embodiment of the invention is thus produced. It can optionally also be provided with handles for gripping and transporting.
  • FIG. 3a to 5c we will now refer to figures 3a to 5c to describe how the bag of Figures 1a to 2c can be carried out according to a conventional manufacturing process.
  • the different work stations have not been shown, but it is possible to understand the different stages of manufacture from a roll R of sheet similar or identical to sheet F1.
  • the first step may consist in making pre-cuts or weakening of the sheet so as to form the frangible zones F15.
  • An optional second step can consist of depositing and fixing on the sheet two handles P, more clearly visible on the figure 4a .
  • a first pair of bellows elements E1 as visible on the Figures 4b and 4c , can be attached and fixed in the folded state on the sheet straddling two frangible zones F15.
  • the other two bellows elements E1 can then be attached and fixed on the sheet straddling two frangible zones F15, so that the four bellows elements E1 are then in place on the sheet.
  • a bellows element E1 is attached in the folded state and fixed on the sheet of the roll at the level of two fixing zones Z14 and Z15 which extend along and on either side of a frangible zone F15.
  • These zones Z14 and Z15 can be coated with glue before returning the bellows element E1 and fixing it on its areas glued by these two fixing flaps S14 and S15.
  • FIG. 6a the bag B1 is seen in its final state of use with the bottom disposed flat and the short lateral sides F13 substantially or completely unfolded, so that the bag B1 constitutes a storage space formed by the internal walls of the bottom F11 and the lateral sides F12 and F13 of the sheet F1.
  • articles such as ready meals and drinks, can be placed inside the bag B1 on the bottom F11.
  • the bag B1 then has a completely conventional configuration for a tablecloth. Because the frangible areas are easily divisible and the bag, when unfolded, has the shape of a rectangle with rounded edges without breaks (and not a cross), it is not useful to take out the contents of the bag to switch from bag mode to tablecloth mode.
  • a main component of the bag is a sheet F2 forming sections F20, two large lateral sides F22 and two small lateral sides F23.
  • the sheet F2 also includes an assembly tab F26 and has fold lines F24.
  • the sheet F2 comprises two frangible zones located at the level of the short lateral sides F23. These frangible zones each comprise two frangible lines F25a and F25b which are arranged relative to each other by forming a right angle or a square. One end of the frangible lines F25a, F25b touches a face F20, while they meet at a junction point F25d, which is here located substantially one third of the width of the side wall F23. According to the invention, an additional frangible segment F25c can extend from the junction point F25d to the free edge of the lateral side F23, as can be seen on the figure 7a . It can thus be said that the frangible zone on a lateral side F23 has a Y-shaped configuration. As in the first embodiment of the invention, the frangible zones can be produced by reducing the wall thickness from sheet F2 or by precuts.
  • the frangible segment F25c can be made in the form of a strip or tear-off tab on which the user can pull.
  • This bag B2 comprises two bellows elements E2 which are produced from a sheet of rectangular shape whose length corresponds to four times the width. Thus, the sheet can be delimited in four squares which can each be separated in two along their diagonal to form right isosceles triangles.
  • the shutter element E2 comprises eight isosceles right triangles formed by four squares whose diagonals extend in a zigzag. Among these eight isosceles right triangles, two pairs of adjacent isosceles right triangles S21, S22 can be identified which are connected together by fold lines S23. Each pair of triangles forms a large isosceles right triangle which can be articulated at the fold line S23.
  • the two large isosceles right triangles are connected only at their 45 ° point.
  • the other four isosceles right triangles form fixing flaps S24, S25 intended to be fixed, for example by gluing or welding, on the sheet F2 at the level where they form the frangible lines F24a and F25b.
  • each bellows element E2 occupies substantially one third of the total surface of the lateral side F23. It can also be noted that the bellows elements E2 do not protrude either on the sides F20 or on the large lateral sides F22, or on the tongue assembly F26: they are fully inscribed inside the lateral sides F23.
  • the small lateral side F23 defines four distinct fixing zones, namely two pairs of fixing zones Z24 and Z25 extending along and on either side of the frangible lines F25a and F25b.
  • the fixing flaps S24 will be fixed on the fixing zones Z24, while the fixing flaps S25 will be fixed on the fixing zones Z25.
  • FIG 9a we see the bag B2 according to the second embodiment of the invention. More particularly, we see the lateral side F23 with its two frangible lines F25a and F25b which connect at the level of the junction point F25b from which extends the frangible segment F25c which goes to the top of the bag.
  • the figure 9b shows a detail of the interior of the bag at which we can see a bellows element E2 fixed on the inner wall of the lateral side F23.
  • a user can then pull on the frangible segments F25c to tear the lateral side 23 up to the junction point F25d. Continuing the traction on the segment F25c, the frangible lines F25a and F25b will give way so as to be able to open the bag, in a configuration represented on the figure 9c .
  • the user achieves the fully unfolded or deployed configuration shown on the figure 9d .
  • sectioning wires having a gripping end which the user can grasp to pull on it strong enough to cut the lateral side.
  • These wires can be fixed, for example loosely glued, on the internal wall of the lateral sides with the grip end projecting from the bag.
  • the bags B1 and B2 comprise bellows elements E1, E2 which are attached and fixed in the folded state on a sheet which is then profiled, assembled and folded to form a usable bag.
  • the bellows elements E1 and E2 are fixed astride or on either side of frangible lines or zones, which the user can easily break to unfold or deploy the bag in the form of a suitable sheet.
  • the present invention has been illustrated with reference to bags which are produced by forming a continuous cylinder which will constitute the four lateral sides of the bag and of which a part will be folded to constitute the bottom.
  • the present invention can also be implemented in other bag architectures, insofar as it is possible to attach and fix the bellows elements in the folded state on a sheet constituting the bag.
